+## ⚙️ 环境配置
+
+### 重要环境变量
+
+```bash
+# 服务器配置
+PORT=8080                    # 服务器端口
+DEBUG=true                   # 开启调试模式
+
+# Haiku 快捷方式（可选）
+HAIKU_BASE_URL=https://api.anthropic.com/v1
+HAIKU_MODEL=claude-3-haiku-20240307
+
+# CORS 配置
+CORS_ALLOW_ORIGIN=*
+CORS_ALLOW_METHODS=POST,GET,OPTIONS,PUT,DELETE
+CORS_ALLOW_HEADERS=Accept,Content-Type,Authorization,x-api-key
+```
+
+### 配置加载顺序
+1. `.env` 文件
+2. 系统环境变量
+3. 默认值
+
+## 🌐 API 使用说明
+
+### URL 格式
+```
+/<协议>/<域名>/<路径>/<模型名>/v1/messages
+```
+
+### 使用示例
+
+```bash
+# DeepSeek API
+POST /https/voapi.16931.com/openai/v1/deepseek-v3-fast/v1/messages
+
+# Groq API
+POST /https/api.groq.com/openai/v1/llama3-70b-8192/v1/messages
+
+# Gemini API
+POST /https/generativelanguage.googleapis.com/v1beta/gemini-1.5-pro/v1/messages
+
+# Haiku 快捷方式（需要设置环境变量）
+POST /haiku/v1/messages
+```
+
+### 请求头部
+代理服务器支持以下 API 密钥头部格式：
+- `x-api-key: your-api-key`
+- `Authorization: Bearer your-api-key`
+- `anthropic-api-key: your-api-key`
+
+## 🔄 工作流程
+
+1. **接收请求**：Claude CLI 发送 Claude API 格式的请求
+2. **解析 URL**：从路径中提取协议、域名、路径和模型信息
+3. **格式转换**：将 Claude 请求格式转换为 OpenAI 格式
+4. **转发请求**：向目标 API 发送转换后的请求
+5. **处理响应**：将 OpenAI 响应转换回 Claude 格式
+6. **返回结果**：将转换后的响应返回给客户端
+
+## 🛠️ 开发和测试
+
+### 本地开发
+```bash
+# 1. 安装依赖
+go mod tidy
+
+# 2. 配置环境变量
+cp .env.example .env

+# 3. 运行服务器
+go run main.go
+```
+
+### 健康检查
+```bash
+curl http://localhost:8080/
+
+# 预期响应
+{
+  "message": "Claude to OpenAI API Proxy",
+  "version": "1.0.0",
+  "environment": "debug"
+}
+```
+
+### 调试技巧

+# Claude to OpenAI API Proxy
+
+🔥 一个强大的Go代理服务器，将Claude API格式的请求无缝转换为OpenAI API格式，使Claude CLI能够与任何OpenAI兼容的服务通信。
+
+**部署在 Hugging Face Space 上的容器化应用**
+
+## ✨ 功能特性
+
+- **动态路由**：无需修改代码，通过URL路径动态指定目标API和模型
+- **全功能API兼容**：完全支持Claude的`/v1/messages`端点，包括流式和非流式响应
+- **Tool Calling转换**：智能转换Claude的tools格式为OpenAI格式
+- **Haiku模型快捷方式**：支持环境变量配置固定路由
+- **一键配置脚本**：交互式配置Claude CLI工具
+- **环境变量配置**：支持.env文件进行本地开发配置
+
+## 🔬 工作原理
+
+### 动态路由格式
+```
+https://<代理地址>/<协议>/<目标API域名>/<路径>/<模型名称>/v1/messages
+```
+
+### 处理流程
+1. 解析URL提取目标API和模型信息
+2. 转发`x-api-key`头部作为`Authorization: Bearer <key>`
+3. 将Claude格式请求转换为OpenAI格式
+4. 发送到目标API的`/chat/completions`端点
+5. 将OpenAI响应转换回Claude格式
+
+## 🚀 快速开始
+
+### 本地开发
+
+1. 克隆项目：
+```bash
+git clone <repository-url>
+cd openai2claudecode
+```
+
+2. 配置环境变量：
+```bash
+cp .env.example .env
+# 编辑 .env 文件设置您的配置
+```
+
+3. 安装依赖：
+```bash
+go mod tidy
+```
+
+4. 运行服务器：
+```bash
+go run main.go
+```
+
+服务器将在`http://localhost:8080`启动。
+
+### 使用配置脚本
+
+运行一键配置脚本来设置Claude CLI：
+```bash
+./claude_proxy.sh
+```
+
+脚本会引导您：
+- 安装Claude CLI（如果需要）
+- 选择API服务（Google Gemini、Groq、OpenAI等）
+- 配置API密钥
+- 设置代理URL
+- 测试配置
+
+### Docker部署
+
+1. 构建Docker镜像：
+```bash
+docker build -t claude-proxy .
+```
+
+2. 运行容器：
+```bash
+docker run -p 8080:8080 \
+  -e HAIKU_BASE_URL=https://api.anthropic.com/v1 \
+  -e HAIKU_MODEL=claude-3-haiku-20240307 \
+  -e DEBUG=false \
+  claude-proxy
+```
+
+## 📖 使用示例
+
+### Google Gemini
+```bash
+curl -X POST http://localhost:8080/https/generativelanguage.googleapis.com/v1beta/gemini-1.5-pro/v1/messages \
+  -H 'Content-Type: application/json' \
+  -H 'x-api-key: YOUR_GEMINI_API_KEY' \
+  -d '{
+    "model": "gemini-1.5-pro",
+    "max_tokens": 1000,
+    "messages": [{"role": "user", "content": "Hello!"}]
+  }'
+```
+
+### Groq
+```bash
+curl -X POST http://localhost:8080/https/api.groq.com/openai/v1/llama3-70b-8192/v1/messages \
+  -H 'Content-Type: application/json' \
+  -H 'x-api-key: YOUR_GROQ_API_KEY' \
+  -d '{
+    "model": "llama3-70b-8192",
+    "max_tokens": 1000,
+    "messages": [{"role": "user", "content": "Hello!"}]
+  }'
+```
+
+### OpenAI
+```bash
+curl -X POST http://localhost:8080/https/api.openai.com/v1/gpt-4/v1/messages \
+  -H 'Content-Type: application/json' \
+  -H 'x-api-key: YOUR_OPENAI_API_KEY' \
+  -d '{
+    "model": "gpt-4",
+    "max_tokens": 1000,
+    "messages": [{"role": "user", "content": "Hello!"}]
+  }'
+```
+
+### 流式响应
+添加`"stream": true`到请求体中启用流式响应：
+```json
+{
+  "model": "gpt-4",
+  "max_tokens": 1000,
+  "messages": [{"role": "user", "content": "Hello!"}],
+  "stream": true
+}
+```
+
+### Tool Calling
+```json
+{
+  "model": "gpt-4",
+  "max_tokens": 1000,
+  "messages": [{"role": "user", "content": "What's the weather like?"}],
+  "tools": [
+    {
+      "name": "get_weather",
+      "description": "Get the current weather",
+      "input_schema": {
+        "type": "object",
+        "properties": {
+          "location": {"type": "string"}
+        },
+        "required": ["location"]
+      }
+    }
+  ]
+}
+```
+
+## ⚙️ 配置
+
+### 环境变量
+
+创建`.env`文件来配置本地开发环境：
+
+```bash
+# 服务器配置
+PORT=8080
+DEBUG=true
+
+# Haiku模型快捷方式（可选）
+HAIKU_BASE_URL=https://api.anthropic.com/v1
+HAIKU_MODEL=claude-3-haiku-20240307
+
+# CORS配置（可选）
+CORS_ALLOW_ORIGIN=*
+CORS_ALLOW_METHODS=POST,GET,OPTIONS,PUT,DELETE
+CORS_ALLOW_HEADERS=Accept,Content-Type,Content-Length,Accept-Encoding,X-CSRF-Token,Authorization,x-api-key,anthropic-version
+```
+
+### Haiku快捷方式
+
+设置环境变量后，可以使用简化的URL：
+```bash
+# 然后可以使用包含"haiku"的任何路径
+curl -X POST http://localhost:8080/haiku/v1/messages \
+  -H 'Content-Type: application/json' \
+  -H 'x-api-key: YOUR_ANTHROPIC_API_KEY' \
+  -d '{...}'
+```
+
+## 🔧 开发
+
